Rule Guided Behaviour
Simple Cued Rules
-
-
Wise & Murray (1996)
Hippocampal ablations impaired the learning of new visuomotor mappings but not the performance of established ones.
Canavan et al (1989)
Lesions in the thalamus disrupting thalami-cortical loops also impaired learning of visuomotor mappings.
Wise & Murray (2000)
Directional selectivity of SEF neurons gradually increased with learning to associate a cue with particular directions.

Monkey Dissociations
-
-
OFC, ACC and PS all impaired on rule shifts: investigated underlying nature of deficits by looking at specific tasks.

Frontopolar Cortex
Boschwin (2015)
FPC lesions impaired learning of a new abstract rule but, following correction were able to learn it at same rate as controls.

Mansouri (2015)
Monkeys with FPC lesions were better at performing WCST when there were interruptions such as free reward or distractors

Cued Abstract Rules
-
-
Wallis (2001)
-
Showed that PFC, PMC ad dorsal striatum all showed rule selective activity and PFC reflected encoding of this rule
-
Uncued abstract rules
When rules are not specified explicitly and one must decide for oneself when it is appropriate to act.

Bentgesson et al (2009)
-
Self generated with instructed showed dlPFC selectively responded to self generated but not instructed.
Strategies
Wise (2008)
-
Cue: response to target: unlimited chances to find target, followed by repeated cue or different cue.
